How about:
bool equal(R1, R2) : std.range
if (isInputRange!R1 && isInputRange!R2)
{ ... }
It's nice and concise, and you could in theory also allow
multiple imports with a comma
bool equal(R1, R2) : std.range, std.traits
if (isInputRange!R1 && isInputRange!R2 && isArray!R2)
{ ... }
breaks possible selective import. if both modules exports some
symbol, we will need to selectively import and/or rename it.
The with keyword then?
bool equal(R1, R2)
with (std.range : isInputRange, isOutputRange) && (std.stdio :
writeln) && (std.algorithm)
if (isInputRange!R1 && isInputRange!R2)
{ ... }
A problem with that is that it reads "bool equal with std.stdio
if something", suggesting something decides whether or not to
import std.stdio.
